From a1b5a24fccc83430bb1fa6e0f9925fb8328abd34 Mon Sep 17 00:00:00 2001 From: Jesse Brandeburg Date: Wed, 13 Apr 2016 03:08:29 -0700 Subject: i40e: Use consistent type for vf_id The driver was all over the place using signed or unsigned types for vf_id, when it should always be signed. This fixes warnings of type unsafe comparisons from gcc with W=2.
